Struct bitcoin::blockdata::transaction::OutPoint [−][src]
pub struct OutPoint { pub txid: Sha256dHash, pub vout: u32, }
A reference to a transaction output
Fields
txid: Sha256dHash
The referenced transaction's txid
vout: u32
The index of the referenced output in its transaction's vout
Methods
impl OutPoint
[src]
impl OutPoint
pub fn null() -> OutPoint
[src]
pub fn null() -> OutPoint
Creates a "null" OutPoint
.
This value is used for coinbase transactions because they don't have any previous outputs.
pub fn is_null(&self) -> bool
[src]
pub fn is_null(&self) -> bool
Checks if an OutPoint
is "null".
Examples
use bitcoin::blockdata::constants::genesis_block; use bitcoin::network::constants::Network; let block = genesis_block(Network::Bitcoin); let tx = &block.txdata[0]; // Coinbase transactions don't have any previous output. assert_eq!(tx.input[0].previous_output.is_null(), true);
